The Wacker Neuson Upper Mass is a genuine OEM component designed for the VP1340A, VP1550A, and VP2050A series single direction vibratory plates. Sourced directly through Wacker Neuson, this part meets the exact specifications of the original component it replaces. Confirmed fitment spans the full VP1340A, VP1550A, and VP2050A model families, covering both standard and AW variants sold in the US and international markets.
Key Features
- OEM Mass Geometry and Weight Tolerance — Manufactured to the original eccentric mass specifications, ensuring the correct centrifugal force output that the machine's compaction rating depends on.
- Direct Drop-In Replacement — Engineered to the original mounting interface so the upper mass seats and secures exactly as the factory component did, with no rework to surrounding hardware.
- Broad VP-Series Compatibility — Fits VP1340A, VP1340Aw, VP1550A, VP1550Aw, VP2050A, and VP2050Aw vibratory plate models, including US-spec variants.
- Compaction Performance Restored — A worn or damaged upper mass disrupts the vibration amplitude of the plate, leading to uneven compaction. Replacing it with the correct OEM part restores rated compaction output.
- Genuine Wacker Neuson Part — Backed by Wacker Neuson's OEM supply chain, part number 5100025664 carries the same material grade and dimensional accuracy as the part that left the factory.
The upper mass is a core element of the vibratory exciter assembly in a single direction vibratory plate. As it rotates, it generates the centrifugal force that drives the plate's compaction action — without the correct mass geometry and weight, the machine cannot produce its rated amplitude or compaction depth. When the upper mass becomes cracked, worn, or out of balance, operators will notice reduced compaction performance, increased vibration irregularity, and accelerated wear on surrounding exciter components. Replacing it promptly with a correctly specified part is essential to maintaining consistent, effective compaction results on the job.
